This invention relates to that type of dump a side of the brackets 2 and pivot upon the shaft bodies used for hauling sand, gravel, dirt or 3 permitting the body 4 to be tilted as shown other like materials and that is unloaded by in Figure 2.

It will be noted in Figure 1 that, when the body 4 is in the position shown, the end of the rod 15 and designated by the numeral 15 is not in alignment with the pivotal point 13 of the lever 13, but is slightly lower. This is important as it locks the mechanism and prevents pressure of the contents of the body on the end-gate from throwing the mechanism and dumping the load before it is desired to do so. It is also evident that the length of the rod 15 must be just sufiicient to close the end-gate and permit the lever 13 to come to rest on the lower part of therstop 27, otherwise the lever would not'come to rest at the proper point.

It is, of course, evident that my invention is susceptible. to various modifications and changes which would be within the spirit of this invention withoutdeparting'from the scope of the following claim.

WhatI' claim is:

The combination with a vehicle chassis, of a body pivoted thereon, a gate'pivoted at the rear of said body, and means for releasably locking said body to said-chassis and to-said gate, said means comprising a hand-lever pivoted to the side and near the front of said body, a rear rock. shaft journaled on said body below said gate, said rock shaft having one of its ends forming an arm for engaging said gate and havingits opposite end forming a rear operating lever, a rear connecting rod. having its ends pivoted respectively to the free end of said rear operating-lever and to'said hand lever. intermediate the'ends. of saidhand lever, a front rock shaft journaled on said body at the front endof said body, an eye projecting from said chassis, said front rock shaft having one of'its ends forming a hook for engaging said; eye and having its opposite end forming af-ront operatinglever, a frontconnecting rod having its ends pivotedrespectively to the 'free end of said front operating lever and to said hand lever, whereby the rearwardmovement of saidrhand lever. operates to simultaneously release said vhook from said eye and said' arm from said gate to permit the pivoting ofsaid body on said chassisa'nd thedumpingofthe contents of saidbody.

Intestimony whereof I afiix my signature.
